We were entrusted with the task of tending the camels. On my turn when I came back in the evening after grazing them in the pastures, I found Messenger of Allah ﷺ stand and address the people. I heard these words of his: If any Muslim performs ablution well, then stands and prays two rak'ahs setting about them with his heart as well as his face, Paradise would be guaranteed to him. I said: What a fine thing is this! And a narrator who was before me said: The first was better than even this. When I cast a glance, I saw that it was 'Umar who said: I see that you have just come and observed: If anyone amongst you performs the ablution, and then completes the ablution well and then says: I testify that there is no god but Allah and that Muhammad is the servant of Allah and His Messenger, the eight gates of Paradise would be opened for him and he may enter by whichever of them he wishes.  

كَانَتْ عَلَيْنَا رِعَايَةُ الإِبِلِ فَجَاءَتْ نَوْبَتِي فَرَوَّحْتُهَا بِعَشِيٍّ فَأَدْرَكْتُ رَسُولَ اللَّهِ ﷺ قَائِمًا يُحَدِّثُ النَّاسَ فَأَدْرَكْتُ مِنْ قَوْلِهِ مَا مِنْ مُسْلِمٍ يَتَوَضَّأُ فَيُحْسِنُ وُضُوءَهُ ثُمَّ يَقُومُ فَيُصَلِّي رَكْعَتَيْنِ مُقْبِلٌ عَلَيْهِمَا بِقَلْبِهِ وَوَجْهِهِ إِلاَّ وَجَبَتْ لَهُ الْجَنَّةُ قَالَ فَقُلْتُ مَا أَجْوَدَ هَذِهِ فَإِذَا قَائِلٌ بَيْنَ يَدَىَّ يَقُولُ الَّتِي قَبْلَهَا أَجْوَدُ فَنَظَرْتُ فَإِذَا عُمَرُ قَالَ إِنِّي قَدْ رَأَيْتُكَ جِئْتَ آنِفًا قَالَ مَا مِنْكُمْ مِنْ أَحَدٍ يَتَوَضَّأُ فَيُبْلِغُ أَوْ فَيُسْبِغُ الْوُضُوءَ ثُمَّ يَقُولُ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا عَبْدُ اللَّهِ وَرَسُولُهُ إِلاَّ فُتِحَتْ لَهُ أَبْوَابُ الْجَنَّةِ الثَّمَانِيَةُ يَدْخُلُ مِنْ أَيِّهَا شَاءَ  

Verily the Messenger of Allah ﷺ said and then narrated (the hadith) like one (mentioned above) except (this) that he said: He who performed ablution and said: I testify that there is no god but Allah, the One, there is no associate with Him and I testify that Muhammad is His servant and His Messenger.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ فَذَكَرَ مِثْلَهُ غَيْرَ أَنَّهُ قَالَ مَنْ تَوَضَّأَ فَقَالَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ
